A House Divided

Divisions abound in the ER as the aftermath of Luka's and Pratt's actions are felt. A patient's call creates friction between Luka and Abby. A contentious family case leads Gates and Ray differ over treatment of one child, while Luka and Abby clash when she needs help with the other. An unauthorized phone call has serious implications for Pratt. Ben takes things to the next level with Sam, but Sam's cautious, and Ray wonders if he's lost his chance with Neela.
